{{- if contains .Values.service.type "LoadBalancer" }}
{{- if not .Values.auth.clientPassword }}
-------------------------------------------------------------------------------
 WARNING

    By specifying "serviceType=LoadBalancer" and not specifying "auth.enabled=true"
    you have most likely exposed the ZooKeeper service externally without any
    authentication mechanism.

    For security reasons, we strongly suggest that you switch to "ClusterIP" or
    "NodePort". As alternative, you can also specify a valid password on the
    "auth.clientPassword" parameter.

** Please be patient while the chart is being deployed **

ZooKeeper can be accessed via port 2181 on the following DNS name from within your cluster:

    {{ template "common.names.fullname" . }}.{{ template "zookeeper.namespace" . }}.svc.{{ .Values.clusterDomain }}

To connect to your ZooKeeper server run the following commands:

    export POD_NAME=$(kubectl get pods --namespace {{ template "zookeeper.namespace" . }} -l "app.kubernetes.io/name={{ template "common.names.name" . }},app.kubernetes.io/instance={{ .Release.Name }},app.kubernetes.io/component=zookeeper" -o jsonpath="{.items[0].metadata.name}")
    kubectl exec -it $POD_NAME -- zkCli.sh

To connect to your ZooKeeper server from outside the cluster execute the following commands:

{{- if contains "NodePort" .Values.service.type }}

    export NODE_IP=$(kubectl get nodes --namespace {{ template "zookeeper.namespace" . }} -o jsonpath="{.items[0].status.addresses[0].address}")
    export NODE_PORT=$(kubectl get --namespace {{ template "zookeeper.namespace" . }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "common.names.fullname" . }})
    zkCli.sh $NODE_IP:$NODE_PORT

{{- else if contains "LoadBalancer" .Values.service.type }}

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace {{ template "zookeeper.namespace" . }} -w {{ template "common.names.fullname" . }}'

    export SERVICE_IP=$(kubectl get svc --namespace {{ template "zookeeper.namespace" . }} {{ template "common.names.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
    zkCli.sh $SERVICE_IP:2181

{{- else if contains "ClusterIP" .Values.service.type }}

    kubectl port-forward --namespace {{ template "zookeeper.namespace" . }} svc/{{ template "common.names.fullname" . }} 2181:2181 &
    zkCli.sh 127.0.0.1:2181
